www.ti.com Purpose of This Document 1 Purpose of This Document This user's guide describes how to use the TAS5601 evaluation module (EVM) to evaluate performance of the TAS5601 device. The document contains the following. • Details of how to properly set up an MC5601 modulator kit. • Details of how to install and use the GUI to program the TAS5601 2 Overview The TAS5601EVM evaluation module (EVM) demonstrates the TAS5601 device from Texas Instruments.
PAGE 4
www.ti.com Overview Figure 2. EVM Controller Board (MC5601) The TAS5601EVM is a complete 2-channel digital audio amplifier system. Also included in the kit is a MC5601 board that includes a USB interface, a digital input (SPDIF), analog inputs via the ADC, and other features like a mute function and power down. The TAS5601EVM can be used as a stand-alone board by wiring it into a system or it can be connected to the MC5601 board for a complete evaluation platform.

www.ti.com Installation • • Connect the left speaker wires to the corresponding metal binding posts marked J2 and J4 on the TAS5601EVM board. Connect the right speaker wires to the corresponding metal binding posts marked J6 and J8 on TAS5601EVM board. For SE: • Connect the four sets of speaker wires to the pairs J2-J3, J4-J5, J6-J7, and J8-J9. 3.2.3 USB Interface The TAS5601 registers are accessed through I2C bus lines SDA and SCL.
PAGE 7
www.ti.com Using the EVM Software 4 Using the EVM Software The EVM software provides access to the TAS5706 configuration and status registers through a GUI window with 7 tabs for the various EVM parameters. 4.1 Getting Started Open the zip file (.zzp) on the installation CD shipped with the EVM. Extract the files and run the setup.exe file to install the EVM software. After the GUI is installed, power up the board, and connect the USB cable.
